This system names\nwhich referral a care-gap criterion is asking about, so that \"has this patient been referred for\npulmonary rehabilitation in the last two years\" can be answered without inferring a programme from\na destination specialty.\n\n**Content is a fragment.** Membership is minted by clinical criteria content and changes on that\ncontent's cadence, not on this guide's, so a code absent from this list may still be in the system.\nBind extensible.",

A referral to a pulmonary rehabilitation programme: the supervised exercise and education programme recommended for symptomatic chronic obstructive pulmonary disease. Distinct from a referral to respirology, which is a specialist opinion rather than a programme, and which a criterion asking for rehabilitation is not satisfied by. WHAT THE DUPLICATION ACTUALLY IS, because it is not only that SNOMED has the concept: this system codes the REFERRAL ACT where SNOMED codes the SERVICE the act requests. Coding the service dissolves the overlap rather than resolving it -- there is then one coded fact, in a published vocabulary, and the act is described by the resource that carries it. SNOMED has three sibling rehabilitation concepts, so the same move covers the neighbours this system would otherwise grow. Retained because stored referrals carry this code.",
